6 Claims.

This invention relates to torch burners for use on highway torches, vehicle flares, etc. and has for its object to provide a new and improved construction for such a burner.

This and other objects of this invention will become more readily apparent from the detailed description thereof which follows, reference being had to the accompanying drawing in which Figure 1 is a top plan view of the torch burner.

Figure 2 is a vertical cross section of the burner, the section being taken on the line 2-2 of Figure 1.

Figure 3 is a vertical longitudinal section of the burner, the section being taken on the line 3-3 of Figure 1.

Figure 4 is a vertical cross section of the burner, the section being taken on the line 4-4 of Figure 1.

Figure 5 is a horizontal sectional view, the section being taken on the line 5-5 of Figure 3.

In the several figures of the drawing like reference numerals indicate like parts.

The torch burner, forming the subject matter of our present invention, is an improvement of the burner illustrated in our prior application Serial No. 757,770, filed December 17, 1934.

As illustrated in the several figures of the drawing the hollow body I of the torch burner extends horizontally over the vertical wick holder 2 which comprises a vertically arranged cylindrical duct provided with one or more spiral wick holding ridges 3, 3 on the inside thereof. The wick holder 2 projects from the flanged base 4 with which the burner is mounted and locked to the fount of the torch (not shown) as shown and described in our previous application, above referred to.

The wick of the burner, which is shown in dotted lines in Figures 2 and 3 and indicated by reference numeral I4, extends thru the wick holder so that by turning it in either one or the other direction, the spiral ridges 3, 3 feed the wick up or down therein. The wick is made to project approximately half way into the central portion of the horizontal body portion of the burner which is widened in our present construction so as to provide free space around the entire wick and enlarge the combustion chamber. The ends of the horizontal body portion of the burner are provided with the vertical ducts or flues 5, 5 which are open at the top and bottom and extend across the end of the combustion chamber so as to carry off the products of combustion from the burner, allow the flames of the burner to pass therethru to the outside thereof and admit air for the combustion of the oil when the normal flow of air thru the air inlets 6 and l is restricted and is not suflicient to support the burner flame. The air inlet openings 6 and I are long and narrow and are located in the bottom of the combustion chamber at opposite sides of 'ne wick between the vertical flues 5, 5. The widened combustion'chamber is flat at the bottom and overhangs the outside of the wick holder 2 between the flues 5, 5 and the air inlets 6 and 1 1 are located in the flat bottom of the combustion chamber and pass vertically therethru parallel to the flues 5, 5. In this way the side walls of the horizontal body of the torch burner are left imperforate to bafiie the wind from any direction. No matter from what direction the wind is blowing air under pressure can therefore not enter the combustion chamber except by blowing into the vertical flues 5, 5 at the top or bottom thereof. When this takes place the flow of air however is restricted because the wind at best strikes the burner at an angle to the flues and never blows directly down into the top or up from the bottom of the flues. In restricting the flow of the air, as above described, the force 25 of the wind is broken so that the Wind entering one of the flues, no matter from what direction, will simply carry the flame of the burner thru the open end or ends of the other flue. The air inlet openings are narrow and are located at 3 the bottom on either side of the combustion chamber between the flues but out of line therewith so that no direct force of air can blow thru them and disturb the combustion of the burner. Only fairly quiescent air will thus enter the air 3 inlets 6 and l for the combustion of the burner and even such air will not directly come in contact with the wick because of the spacing of the air inlets from opposite sides thereof.

This new and improved construction has been 4 found to materially increase the efliciency of the torch burner because of the increased size of the combustion chamber and the location and design of the air inlets leading thereinto. It has increased the dependability of the torch burner by baflling the wind from any direction and shielding the wick from rain or water. The torch burner is thus made windproof, rainproof and splashproof and will burn under any and all weather conditions and provides a safety or signal light that is unsurpassed for its dependability.

We claim:

1. A torch burner comprising a hollow body member surrounded by imperforate side walls, a wick holder in the bottom of said hollow body member adapted to hold a wick in place therein, said hollow body member having flame openings in the top and bottom substantially in line with each other offset from said wick holder and having air inlet openings in the bottom thereof intermediate the flame openings.

2. A torch burner comprising a vertically arranged wick holder, a hollow body member surrounded by imperforate side walls extending across the top of said wick holder and overhanging all sides thereof, said hollow body member having a flame opening in the top and bottom at opposite overhanging ends thereof and having air inlet openings in the bottom of the overhanging sides thereof intermediate the flame openings.

3. A torch burner comprising a hollow body member having a substantially elliptical horizontal cross section with imperforate side walls, a Wick holder centrally of said hollow body member, the bottom of said hollow body member having flame openings in the reduced ends thereof and having air inlet openings in the bottom of the wide central portion on opposite sides of the wick holder, and the top of said hollow body member having flame openingsin the narrow ends thereof substantially in line with the flame openings in the bottom thereof.

4. A torch burner comprising a hollow body member with imperforate side walls, a wick holder in the bottom of said hollow body member, the bottom and top of said hollow body member having flame openings therein ofiset from the wick holder and the bottom of said hollow body member having air inlets adjacent to the wick holder so as to provide a combustion chamber in the hollow body member with flame openings in the top and bottom thereof and a protective cover over the wick holder between them.

5. A torch burner comprising an elongated hollow body member having a substantially flat bottom, a horizontally extending top with rounded ends, said body member having flame openings in the top and bottom adjacent the rounded ends thereof, a wick holder in the bottom of said body member below the horizontally extending closed top and the bottom of said body member having air openings leading into the body member so as to have them covered by the horizontally 20 extending closed top.

6. A torch burner as set forth in claim 5 in which the wick holder extends below the bottom of the body member with the flame and air openings in the bottom located on the outside of the 25 wick holder extension.
